iPhone 4s losing data connection multiple times/day

IOS 5.1 Beta 2 has not fixed it ! Cant say too much due to Apple privacy etc, but it was a full 800mb download which beta 1 wasn't (5.5mb). I had high hopes but absolutely no change ! In fact possibly worse !

Really getting hacked off now. Spoke to an O2 guru who just went through the motions (hard reboot, clean sim, try in another phone etc) and in the end said go to your local o2 shop. So just walked into town, went to the o2 shop where they denied all knowledge and weren't particulalrly interested! "Apple dont tell us anything" - whats next?

All the apple shops are heaving with 12 year olds who have no intention or ability of buying anything but just make the place ****!

Carrier not interested !

Is it time for Android ? Iphone 4 was poop (antennagate etc), 4s is no better and now IOS 5 makes it about as useful as a chocolate teapot ! I have spent a lot of money on apple products over the years and recommended them over all competition for years - What do you all think ? If we start bombarding the press who do we email etc ?

I went in yesterday to an Apple store to have them look at my second iphone that is having this problem. They told me it was my carrier but showed them this Forum proving it was not just one carrier. They gave me the run around stating that there are only a hand full of people on that forum bla bla bla. Long story short I litterally walked out of the apple store with my 3rd new phone doing the exact same thing.

So the only common factor that I can think of is the Sim card. That is the one part that has been the same in every phone. Apple does not hand out new SIMs so I am just curious if anyone here has had there SIM changed and if that made a difference. Sprint will not change mine. Yet!

I'm on my second sim and have tried it wedged in a Blackberry and that is fine ! Definatly not Sim related for me at least !

Well there goes that theory. :-( This really *****! My buddies phone works just fine. Of course he bought his when the 4s first hit the shelves. I guess the only thing that it could be is that in certain phones, maybe a newer ones, got bad antennas or something. I just hope this problem gets big enough it hits the media so Apple will look more seriously at it.

I have this issue too, but only at one spot. I listen to Pandora at the gym, and sometimes I'll lose the data connection. If I toggle airplane mode, I can get it back again. Since it only happens at this one spot, I wonder if it has something to do with the cell tower I'm connected to (AT&T).

This is strange. For me, I can do a full restore of the OS, start as a new iphone and still have this problem. Yesterday apple replaced my phone again and I walked out of the store with a new phone, not restored from a backup, no email accounts attached, having this same exact issue. Basiaclly the 3G connection works for about 15-20 minutes, then nothing.

I just found this thread about the new build of iOS 5.0.1. There are posts about modem firmware and data connection issues. I wonder if this new build fixes it?

Here's the whole thread:

http://forums.tipb.com/ios-5-forum/226621-5-0-1-9a406-new-build-number-out-iphon e-4s.html

There is a reference to this:

http://support.apple.com/kb/TS4148

That update is not being pushed to ppl who already have 5.0.1 and besides I think this issue is different from the no connection / no sim issue.

On the email theory, I have the issue and have no exchange accounts setup.

I do have 2 email accounts, but they are both GMail accounts using only username/pw as the setup.

Ditto silver dollars.

I have removed all my email accounts and still have the problem. The only forward progress I have made is that when i synced with itunes last night, it worked for an hour or so and then packed up again ! Normally i get less than a minute !

Other things I have tried and failed with:-

1 Disable automatic carrier selection and lock to my carrier

2 Disable I-message

3 Disable facetime

4 Disable Data-roaming

5 remove I cloud account

I'm just trying to think of anything else that may "Hog" the 3g connection. Any Suggestions ?

One thing I have noticed is that often when the connection dies my carriers name does not appear next to the carrier section in settings, yet after turning airplane mode on and off it reappears. Is this a hint?

What Modem firmware is everyone running ? (Settings > General > About) i'm 1.4.00

Just downgraded from 5.1 beta 2 to the latest build of 5.0.1 and it's worse than ever ! It has now changed the modem software as well ! So that doesn't help !

Spoken to carrier O2 who were very knowledgeable and helpful but could not sort the problem. They also claimed to have no knowledge of it ! Then Spoke to apple who went through the list of things I've already done and told me to get a replacement hand set tomorrow ! They also denied all knowledge ! So either they are playing the corporate game ( which is fine) or, more worryingly they genuinely don't know about it !

I'm posting to support this thread and maybe (but pfft, probably not) get apple to correct this problem. Because it is INDEED a very real problem. Now, it may not affect ALL users, but I was under the impression that apple cares about even just one user. So, please Apple, fix this issue. I am on an iPhone 4S with AT&T running the latest OS. I do have many apps, songs, and videos on my phone, but I already thought that battery loss was the sacrifice there, so I doubt that it's also a loss of data connection. So far my iPhone 4S is the speediest phone I've ever had the pleasure of owning, that sometimes doesn't actually connect speedily to anything, and that can't be a good thing. I look forward to an always there, always reliable connection (as it was with other versions and iPhones), especially when it seems it's on your end of the spectrum to fix.
